Using “forbidden” classes in Java?

My employer needs an extension org eclipse. rse. core. subsystems. The Java class of subsystem for eclipse plug - ins Unfortunately, the access rules of the library that implements it (org. Eclipse. RSE. Ui_3.3.318.201404091445. Jar, if it helps) mark all "prohibitions" that it does not explicitly allow, and the class is not explicitly allowed

I can change the access rules to allow access to this class, but it will cause problems when the plug-in is installed on another machine?

Solution

Eclipse helps to document this clearly

So this is not desirable
